Independent Testing

Crossgrip wind tunnel tests

Crossgrip has undergone independent wind tunnel testing at the School of Aerospace, Automotive and Design Engineering at the University of Hertfordshire. The aim of the tests being to ascertain the effect of wind speeds on Crossgrip Roof Walkway Matting and establish at what wind speeds it might lift away from the roof surface. These lift-off speeds, measured against the Internationally recognised Beaufort Wind Scale, were then compared to likely wind conditions at potential installations. The tests concluded that Crossgrip will remain stable when laid flat on a smooth surface in hurricane force winds just in excess of 100mph. However, Plastex recommends that if wind speeds in excess of 95mph are probable, connecting loops should be welded onto the vinyl membrane.

In some countries temperatures can fall as low as - 40 degrees Celsius. Plastex has therefore had independent cold impact performance tests conducted to establish Crossgrip's performance in sub-zero temperatures. These tests have shown that the product performs extremely well and can generally withstand an impact weight of up to 1.5kgs from a 300mm drop, as opposed to the specification requirement of 100mm, at temperatures of - 40°C. (or/ significant impact weights at sub-zero temperatures of - 40°C)

The product is also UV and chemical resistant with permanent slip resistance.

Crossgrip is therefore the ultimate high level roof walkway matting solution for all weathers and all conditions.
